In your code: 
sub show_form {
  my $c = shift ;
  my $status   = status() ;
  my $message  = get_message() ;
  my $service_name = '' # where do you get this from?!?

  my $template = HTML::Template->new(filename => 'form.tmpl');
  $template->param(
    service_name => $service_name,
    status       => $status,
    message      => $message,
  );

  reset_message; # shouldn't you use parens here?

  my $resp = HTTP::Response->new ;
  $resp->content($template->output) ;
  $c->send_response($resp) ;
}

And the template: 
<html>
  <head>
    <title><tmpl_var service_name> controls</title>
  </head>
  <body>
    <h1 align="center"><tmpl_var service_name> controls</h1>
    <div align="center">
      <table style="border-width: 2px ; border-style: solid">
        <tr align="center">
          <td>
            <form action="/start" method="post">
              <input type="submit" value=" Start " >
            </form>
          </td>
          <td>
            <form action="/stop" method="post">
              <input type="submit" value=" Stop " >
